Jose Morales Delgado had already asked his girlfriend of six months, Jennifer Jaramillo, to the prom.

No drama. She said yes.

But that wasn’t the end of it.

With Skyline High School’s senior prom still several weeks away, Jose wanted to clear a higher hurdle, do something that would wow — or, in this case, prance.

So, he started making plans to surprise Jennifer at school with an elaborate “promposal.”

Fancy prom proposals aren’t exactly new. The first mention of them dates to an article in The Dallas Morning News in 2001. The story highlighted two promposals: A McKinney High School student rewrote the words to a song in Adam Sandler’s The Wedding Singer, and a Plano West senior got on the P.A. at the Tom Thumb where he and his girlfriend worked to pop the question (the two are now married).

Since then, promposals have become less of a rarity. They can range from the mundane — spelling out “Prom?” in chicken nuggets or pizza toppings — to over-the-top: flash mobs, scavenger hunts, helicopter rides.

Jennifer had just left her final class of the day, and was headed for the car. As she walked past the gym, “I heard the music, and then I saw his horse,” Jennifer said. “I was like, ‘Whoa...' ”

A third-generation horse trainer who works at his family’s ranch, Rancho JM, in Dallas, Jose had done similar routines before at parties, charity events and rodeos, working with his friend, Saul Mendoza.

“It’s awesome,” he said of his job. “Working with horses, to be honest, it’s a pretty good job and I enjoy it.”

To his credit, said Skyline principal Janice Lombardi, Jose went to school administrators to get approval to bring the horse on campus.

Lombardi said yes, but only for the end of the school day, so it wouldn’t be too much of a distraction.

An educator for nearly 30 years, Lombardi called Jose’s promposal “the most unique I’ve ever seen” — which is saying something. Almost 1,000 seniors will be invited to Skyline’s senior prom on May 19.
